flux

Updated the official TI datasheet URL and corrected the part description to the 38-pin WQFN REF0038A package; now I’m applying the datasheet-derived pin metadata and grouped-pin modeling.

flux

The six missing grouped power pins are now explicit terminals; I’m checking the generated pads and will align their footprint geometry with the existing grouped land regions if needed.

flux

Completed the datasheet and pin-model updates for TPS25751DREFR, including explicit grouped power pins and aligned footprint alias pads. I also corrected the project description and updated the report: Part Datasheet Review.
Open items:
  • Flux stores the official TI datasheet as a managed uploaded PDF after setting the TI URL; the official source URL is recorded in the report.
  • Pin Group: GPIO is semantically correct but not in the current autocomplete list.
Suggested next steps:
  1. Run/publish the part review flow.
  2. Open the generated symbol/footprint visually to confirm the grouped pins display as desired.
  3. Use this corrected part in downstream USB-C/PD designs.

Part Datasheet Review — TPS25751DREFR
Date: 2026-07-07
Status: Updated after corrective edits
Corrective Edits Completed
  • Updated the part Datasheet URL using the official Texas Instruments TPS25751 datasheet source: https://www.ti.com/lit/ds/symlink/tps25751.pdf.
  • Corrected the project description from the stale 32-pin VQFN wording to the actual TPS25751DREFR package: 38-pin WQFN REF0038A, 4 mm x 6 mm.
  • Added datasheet-derived terminal metadata for all existing pins:
    • Pin Type
    • Pin Description
    • Pin Group
    • Section
    • Terminal Order
  • Added explicit terminals for the previously omitted grouped physical pins:
    • PPHV_21 pin 21
    • PPHV_22 pin 22
    • VBUS_IN_24 pin 24
    • VBUS_IN_25 pin 25
    • VBUS_33 pin 33
    • PP5V_35 pin 35
  • Updated the new grouped-pin footprint pads so they overlay the existing TI REF0038A grouped land regions:
    • pins 20/21/22 share the PPHV land region
    • pins 23/24/25 share the VBUS_IN land region
    • pins 32/33 share the VBUS land region
    • pins 34/35 share the PP5V land region

Pin Modeling Result
The symbol now represents every datasheet pin number 1 through 40, including exposed pads 39 and 40. The grouped physical power pins are modeled as explicit terminals with their own pin numbers while sharing the same grouped copper land geometry in the footprint, matching the REF0038A land-pattern concept.

Verification Notes
  • Project metadata now reports 40 terminal components, matching pins 1–40 including the two exposed pads.
  • New grouped-pin pads were aligned to the existing grouped pad coordinates and sizes rather than left at the default circular pad geometry.
  • Component review checks queried for terminal, pin-number, datasheet, and project metadata categories returned no listed review items at the time of verification.
Remaining Notes
  • Flux stores the official TI datasheet as a managed uploaded PDF URL after setting the official TI link; the official source URL remains recorded here for traceability.
  • Some GPIO pins use Pin Group: GPIO, which is semantically correct even though it is not one of the current autocomplete options returned by the property config.
